Ferritin nanocages are of particular interest as a novel platform for drug and vaccine delivery, diagnosis, biomineralization scaffold and more, due to their perfect and complex symmetry, ideal physical properties, high biocompatibility, low toxicity profiles as well as easy manipulation by genetic or chemical strategies. However, a short half-life is still a hurdle for the translation of ferritin-based nanomedicines into the clinic. Here, we developed a series of rationally designed long circulating ferritin nanocages (LCFNs) with 'Intrinsically Disordered Proteins (IDP)' as a stealth layer for extending the half-life of ferritin nanocages...

High prevalence of vitamin D deficiency has been reported worldwide. Residents of Taiyuan, China, were predicted to be at high risk of vitamin D deficiency due to its high latitude, heavy air pollution, and cultural sun avoidance. This study investigated the vitamin D status of office workers, and explored the potential determinants of capillary 25-hydroxyvitamin D (25(OH)D) concentration as well as the relationship between 25(OH)D and metabolic syndrome. Two hundred participants, aged 20 to 80 years, were recruited...

BACKGROUND CONTEXT: Smartphones have become an integral tool in the daily life of healthcare professionals (Franko 2011). Their ease of use and wide availability often make smartphones the first tool surgeons use to perform measurements. This technique has been validated for certain orthopaedic pathologies (Shaw 2012, Quek 2014, Milanese 2014, Milani 2014), but never to assess sagittal parameters in adult spinal deformity. This study was designed to assess the validity, reproducibility, precision and efficiency of using a smartphone protractor application to measure sagittal parameters commonly measured in adult spinal deformity assessment and surgical planning...

BACKGROUND: The number of older adults residing in assisted living communities is increasing. Despite the benefits of physical activity (PA) on physical and cognitive capacities, and the opportunities for being active offered in these living environments, this population is highly sedentary and more at risk of physical decline. This study aimed to assess the feasibility, the acceptability, and the effects of PA intervention using gerontechnology in assisted living communities. METHODS: Forty-two older adults in 4 assisted living communities were recruited and randomly assigned to an exercise intervention group (EX) or a control group (CON) using a 2:1 ratio...

Granulomas are complex lung lesions that are the hallmark of tuberculosis (TB). Understanding antibiotic dynamics within lung granulomas will be vital to improving and shortening the long course of TB treatment. Three fluoroquinolones (FQs) are commonly prescribed as part of multi-drug resistant TB therapy: moxifloxacin (MXF), levofloxacin (LVX) or gatifloxacin (GFX). To date, insufficient data are available to support selection of one FQ over another, or to show that these drugs are clinically equivalent. To predict the efficacy of MXF, LVX and GFX at a single granuloma level, we integrate computational modeling with experimental datasets into a single mechanistic framework, GranSim...

Campylobacter and Salmonella are leading causes of bacterial gastroenteritis in the United States and are estimated to cause >1 million episodes of domestically acquired illness annually (1). Campylobacter and Salmonella are primarily transmitted through contaminated food, but animal-to-human and human-to-human transmission can also occur (2,3). Although occupationally acquired infections have been reported, occupational risk factors have rarely been studied. In 2015, the Occupational Safety and Health Administration (OSHA) identified 63 suspected or confirmed cases of Campylobacter infection over 3...

Physicians' experience with high quality training in breastfeeding during their medical education is historically varied. The process of becoming a board-certified physician entails more than 20 years of education, and although medical school and residency training timelines and courses are relatively standardized across the United States and even internationally, breastfeeding education varies greatly across schools and programs. The Academy of Breastfeeding Medicine (ABM) exists, in part, because historically, physicians have received too little clinical training in breastfeeding and infant nutrition...

Sexual minority males are an at-risk group for developing skin cancer. Elevated rates of skin cancer among this population are thought to be driven by excess indoor tanning; however, motivations to indoor tan among this population are unknown. Theoretically, appearance-based and affect regulation motives may be proximal predictors of increased indoor tanning in this population. The current study tests an integrated biopsychosocial model of indoor tanning behaviors and future intentions among a sample of sexual minority males...

Built and social environments, including one's perception of their environment, are important determinants of health. The intersection of gender and HIV status may complicate the role of neighborhood cohesion in safety, personal well-being, and health outcomes for populations impacted by social and structural inequities. Among women in particular, social cohesion within the neighborhood they reside in may have a greater influence on health outcomes compared to their male counterparts. We sought to examine perception of neighborhood cohesion (validated scale with a range 0-100, with higher scores indicating higher perceived neighborhood cohesion) among women living with HIV, impacted by social-structural inequities, receiving combination antiretroviral therapy, and enrolled in the Longitudinal Investigations into Supportive Ancillary health services (LISA) study in British Columbia, Canada...

Importance: Previous studies of resident attrition have variably included preliminary residents and likely overestimated categorical resident attrition. Whether program director attitudes affect attrition has been unclear. Objectives: To determine whether program director attitudes are associated with resident attrition and to measure the categorical resident attrition rate. Design, Setting, and Participants: This multicenter study surveyed 21 US program directors in general surgery about their opinions regarding resident education and attrition...

The constant regeneration of stomach epithelium is driven by long-lived stem cells, but the mechanism that regulates their turnover is not well understood. We have recently found that the gastric pathogen Helicobacter pylori can activate gastric stem cells and increase epithelial turnover, while Wnt signalling is known to be important for stem cell identity and epithelial regeneration in several tissues. Here we find that antral Wnt signalling, marked by the classic Wnt target gene Axin2, is limited to the base and lower isthmus of gastric glands, where the stem cells reside...

Background The CHA2DS2-VASc score well stratifies the risk for thromboembolic events in non-valvular atrial fibrillation (NVAF) patients. This score may also predict thromboembolic events in sinus rhythm populations. Purpose The purpose of this study was to assess the prognostic role of CHA2DS2-VASc in a Caucasian community population of patients with arterial hypertension and sinus rhythm. Methods A total of 12,599 arterial hypertension residents not receiving anticoagulation were selected from a community population in Trieste between November 2009 and October 2014: 11,159 sinus rhythm and 1440 NVAF patients...

Microsurgery is a technically demanding field with long learning curves. Robotic-assisted microsurgery has the ability to decrease these learning curves. We, therefore, sought to assess the feasibility of robotic-assisted microvascular surgery in a rat model, and whether this could be translated into a worthwhile skills acquisition exercise for residents. Twenty-eight rats underwent microvascular anastomosis. Procedures were performed by a trained microvascular surgeon with no robotic experience (n = 14), or a trained robotic surgeon with no microvascular experience (n = 14)...

BACKGROUND: Obstetric danger signs are not the literal obstetric complications, merely symptoms that are well named by non-clinical personnel. The identification of these danger signs and its relation with complications during pregnancy would increase the capacity of women, their partners and families to seek for timely health care, following the appropriate steps to insure a safe birth and post-partum. The aim of this study was to assess the knowledge of obstetric danger signs and associated factors among pregnant women attending antenatal care in Yirgacheffe town, Gedeo zone, Southern Ethiopia...

The epithelial-to-mesenchymal transition (EMT) is a reversible process comprised of various subprograms via which epithelial cells reduce their intercellular adhesions and proliferative capacity while gaining a mesenchymal phenotype with increased migratory and invasive properties. This process has been well described in several carcinomas, which are cancers of epithelial origin, and is crucial to metastatic tumor cell dissemination and drug resistance. In contrast, the precise role of EMT-related processes in tumors originating from mesenchymal tissues, such as bone and soft-tissues sarcomas, is still largely unclear...

Changing light conditions, caused by the rotation of earth resulting in day and night or growth on the surface or within a substrate, result in considerably altered physiological processes in fungi. For the biotechnological workhorse Trichoderma reesei, regulation of glycoside hydrolase gene expression, especially cellulase expression was shown to be a target of light dependent gene regulation. Analysis of regulatory targets of the carbon catabolite repressor CRE1 under cellulase inducing conditions revealed a secondary metabolite cluster to be differentially regulated in light and darkness and by photoreceptors...

A high hospital utilisation at the end of life (EOL) is an indicator of suboptimal quality of health care. We evaluated the impact of the intensity of different Integrated Cancer Palliative Care (ICPC) plans on EOL acute medical hospitalisation among cancer decedents. Decedents of cancer aged 18-84 years, who were residents in two Italian regions, were investigated through integrated administrative data. Outcomes considered were prolonged hospital stay for medical reasons, 2+ hospitalisations during the last month of life and hospital death...

BACKGROUND: Few studies have empirically investigated factors that define residential aged care units that are perceived as being highly person-centred. The purpose of this study was to explore factors characterising residential aged care units perceived as being highly person-centred, with a focus on organisational and environmental variables, as well as residents' and staff' characteristics. METHODS: A cross-sectional design was used. Residents (n = 1460) and staff (n = 1213) data from 151 residential care units were collected, as well as data relating to characteristics of the organisation and environment, and data measuring degree of person-centred care...
